WASHINGTON — A new shooting game for mobile devices tied to the National Rifle Association is no longer being labeled suitable for preschoolers. "NRA: Practice Range" changed its age recommendation Tuesday from 4 years and up to at least 12 years of age, with an added warning that the game depicts realistic violence.

The game was released after a top NRA executive, Wayne LaPierre, had blamed violent video games, not guns, for contributing to mass shootings. A progressive advocacy group, Courage Campaign, on Tuesday circulated an online petition asking Apple to drop the free mobile application from its store.

The NRA and MEDL Media, which developed the game, did not respond to calls seeking comment. Apple declined to comment.
